Public constructors
AccelerateInterpolator
public AccelerateInterpolator()
Creates a new instance of AccelerateInterpolator with y=x^2 parabola.
AccelerateInterpolator
public AccelerateInterpolator(float factor)
Creates a new instance of AccelerateInterpolator.
| Parameters | |
|---|---|
float factor |
Degree to which the animation should be eased. Setting factor to 1.0f produces a y=x^2 parabola. Increasing factor above 1.0f exaggerates the ease-in effect (i.e., it starts even slower and ends evens faster) |
AccelerateInterpolator
public AccelerateInterpolator(
@NonNull Context context,
@NonNull AttributeSet attrs
)
Creates a new instance of AccelerateInterpolator from XML.
| Parameters | |
|---|---|
@NonNull Context context |
The context. |
@NonNull AttributeSet attrs |
The AttributeSet from XML. |
Public methods
getInterpolation
public @FloatRange(from = 0, to = 1) float getInterpolation(@FloatRange(from = 0, to = 1) float input)
Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction. This interpolated value is then multiplied by the change in value of an animation to derive the animated value at the current elapsed animation time.
| Parameters | |
|---|---|
@FloatRange(from = 0, to = 1) float input |
A value between 0 and 1.0 indicating our current point in the animation where 0 represents the start and 1.0 represents the end |
| Returns | |
|---|---|
@FloatRange(from = 0, to = 1) float |
The interpolation value. This value can be more than 1.0 for interpolators which overshoot their targets, or less than 0 for interpolators that undershoot their targets. |
